GEORGE P. WIGGINTON, OF KALAMAZOO, MICHIGAN, ASSIGNOR TO KALAMAZOO LOOSELEAF BINDER COMPANY, OF KALAMAZOO, MICHIGAN.

- TEMPORARY BINDER.

Application filed April 11, 1925. Serial No. 22,287.

To all whom it may concern:

Be it known that I, GEORGE I. VVIeGiN- TON, a citizen of the UnitedStates, residing at the city and county of Kalamazoo, State of Michigan,have invented certain new and useful In'iprovements in TemporaryBinders, of which the following is a specification.

This invention relates to improvements in temporary binders. 1

The main object of this invention is to provide an improved temporarybinder which is well adapted for the binding of loose record sheets,catalog sheets and the like which is very simple and economical instructure and quickly and easily manipulated to release or introduce thesheets.- 4

Objects pertaining to details and econonies of my invention will.definitely appear from the detailed description to follow.

I accomplish the objects of my invention by, the devices and meansdescribed in the following specification. The invention is to clearlydefined and pointed out in the claims. I

A structure embodying the features of my invention is clearlyillustrated in the accompanying drawing forming a part of thisapplication, in which:

Fig. I is a perspective view of a binder embodying the features of myinvention.

Fig. II is a plan view with the front cover open.

Fig. III is a fragmentary plan view with the sheets thrown forwardlyupon the front or top cover showing the manner of attaching the bindingstrips to the bottom binding bar. 7

Fig. IV is a detail vertical section on a line corresponding to line 1M4of Fig. II.

Fig. V is a fragmentary plan view of the means for adjustably securingthe binding strips.

Fig. VI is a fragmentary section on a. line corresponding to line 6'6 ofFigs. V and VII showing details of the binding strip clamping orsecuring means.

Fig. VII is an enlarged detail section on a line corresponding to line77 of Figs. V

and VI. 2

Fig. VIII is a detail section on a line corresponding to line 8-8 ofFig. VII.

Fig. IX is a plan view of one of the anchor plates for connecting thebind ingstrips to the bottom binding bar.

In the drawing the sectional views are taken looking in the direction ofthe little arrows at the ends of the section lines and similar numeralsof reference indicate similar parts throughout the several views.

Referring to the drawing, 1 and 2 represent the bottom and top coversrespectively of the binder and 3 and f the bindingbars which are securedto the rear edges of the covers by the flexible hinges 5 so that thecovers close over the binding bars when the binder is closed.

The binding strips 6 are preferably formed of tape of suitable strengththe bottom binding bars having slots therein through which the bindingstrips 6 are arranged and to which they are connected by the anchorplates. 8. These anchor plates are formed of sheet metal stampings andhave slots 9 therein through which the binding strips are arranged andsecured by the tongues 10, the plates being thus secured to the stripsso that the strips may be arranged through the openings'or slots of theplates on the outer side of the bar.

The top binding bar has openings 11 therein through which the bindingstrips are arranged and has mounted thereon clamping plates-12 wlthopenings 13 thereln'regv jistering with the openings 11. The front edgesof the openings 13 are turned upwardly and serrated to provide upturnedteeth '14. Clamping members 15 are provided with downwardly projectingpivot ears 16 embracing the downturned pivotears 17 on the, clampingplates and pivoted thereto by the pin 18.- i i v The ears 16 of theclamping plates are arranged so that when the clamping member pivotedthereon is swung forwardly to a position parallel to the clamping platethe binding strip is clamped upon the teethof the clamping plate and issecurely held where clamped. It may be freed, however,

by an upward pull on the binding strip which swings the clamping memberon its pivot freeing the binding strips so that they may be adjusted orremoved as may be desired. i j

The sheets'to be bound indicated at 19 have alined holes 20 ther intoreceive the binding strips. 7

My improved temporary binderis very simple and economical in structureand is especially designed for binders of small sizes and light weight.At the same time ill) in, binding strips disposed, through said,

slots, anchor plates on said binding strips disposed on theouter-sidesotsaidjbottorn binding bar, clamping plates. mounted on the outer side ofsaidtop binding bar and having openings therein registering with saidslots thereof, the front, edges of the openings of said clamping plateshaving upwardly directed teeth, said plates having downwardly projectingpivot earsdisposed in said; slots in said top binding bar, and clampingmembers havingv downwardly projecting pivot ears mounted on said; pivotears of said clampingplates so that said clamping members may be swungforwardly to an approximatelyparallel relationto said clamping platesclam-pingthe-binding strips upon saidteethithe rear edges ot',the;clainpingmembers when closed being in approximately. the plane oftheteeth.
